Hi Xuan,
If you run your program directly, without gdb, does it show
a CA.Client.Exception w/ Context of "ca_search"?
If so, that's the result of the SEVCHK macro that calls ca_pend_io
throwing an exception because one of the PV's didn't connect.
I'm not sure why gdb shows that location in the backtrace, but
I saw the same thing w/ both gdb and valgrind. Possibly something
to do with that being the next line of code to execute if the exception
hadn't been thrown.
It you're not getting a Context of "ca_search", please send the full
output message.
Cheers,
- Bruce
